Add hyperv-keyboard kernel module for Hyper-V Gen2 VM

The synthetic keyboard of a Gen2 Linux VM doesn't work before the
hyperv_keyboard module is loaded. Without it, we can't cancel the media check
phase if boot with rd.live.check option.
Gen1 Linux VM doesn't have the same issue because the host emulates the legacy
i8042 keyboard for Gen1 VM.
